Subject: collapsing unicode white space

Hi everyone,

I need to implement a W3C processing algorithm which states:

10.1.8 Rule for Getting Text Content with Normalized White Space
The rule for getting text content with normalized white space is given =20=

in the following algorithm. The algorithm always returns a string, =20
which MAY be empty.

	=95 Let input be the Element to be processed.
	=95 Let result be the result of applying the rule for getting =
text =20
content to input.
	=95 In result, convert any sequence of one or more Unicode white =
space =20
characters into a single U+0020 SPACE.
	=95 Return result.

The step I'm having problems with is "convert any sequence of one or =20
more Unicode white space characters into a single U+0020 SPACE."

The StringUtils replace() and CharSetUtils squeeze() methods would =20
seem to be best suited for solving this one, but there doesn't seem to =20=

be a set syntax for easily specifying unicode white space chars =20
defined for one thing.

Has anyone else solved a similar problem using commons lang, or should =20=

I consider using something else?

Thanks!

S
